Are all bike handles the same size?
No. Though the internal diameter dimension has been standardized to fit just about any mountain bike handlebar (22mm being the current standard), grips come in a number of different lengths and outer diameters in order to give a more custom fit tailored for the riders preference.
How do I know what size handlebars to get?
If the handlebar you want to use is measured from the inside edge to the other inside edge, just add 2 cms to your shoulder measurement to get the right size. For example, if your shoulder measurement is 38 cms, you need a 40-cm handlebar.
Are all handlebars 22.2 mm?
There are only two current standard sizes: Flat bars have a 22.2 mm (7/8″) grip area diameter. Road (“drop”) bars have a 23.8 mm (15/16″) grip area diameter.
Are handlebars Universal?
– Yes, they are interchangeable, but the process is not simple. There are dozens of handlebar types to suit different rider needs, leverage on the bicycle, and diameter measurements will vary for each.
